This week brings the annual return of the Perseids, one of the most stunning meteor showers of the year, visible from just about anywhere. WHAT: The height of the Perseid shower comes every August, because that's the time our planet passes through a certain debris path.
The Perseids are created by the tiny remnants left behind by comet Swift-Tuttle. The Earth passes through this material once a year, creating a spectacular show as the cometary particles burn up in the atmosphere [Discovery News].
